Heli, TREX 250 PRO DFC Super Combo

In addition to the superior 3GX flybarless system, the T-Rex 250 PRO DFC also incorporated numerous new features based on Align's innovative designs and outstanding manufacturing process, resulting in a helicopter that is overall more stable, easier to fly, and excels in 3D performance.

As a standard equipment of the T-Rex 250 PRO DFC, the popular DFC head features low CG, low wind resistance, providing more direct and precise flying response, with excellent high speed. Frame structure utilizes material integration techniques, allowing perfect assimilation between plastic alloy with carbon fiber, maintaining structure rigidity while simplifying maintenance. Unique gyro/servo integrated mount enabling quick removal, simplifying maintenance while keeping a clean overall aesthetic look. Utilizes highly efficient shaft drive system, effectively minimize tail power output loss. Tail gearbox is an integrated unit with a new rudder control system, with solid construction and zero slop, resulting in more precise control feel.

Although T-Rex 250 PRO is small in size, it’s packed with performance capable of any difficult flight maneuvers. No longer do you need to find a large open space to fly; you can enjoy flying in your backyard or any larger indoor space.
